After a week of insanity, I now have a replacement for my custom world. It is both better and worse than it's predecessor. My previous method was to put down empty lots and gradually edit them now and then, saving the revisions to the bin and then moving them back to CAW. That is apparently how I corrupted the old one. Starting tomorrow, I'm going to create a new couple and play two different versions of the world, one with the new couple where I can work towards enhancing the world, and with my usual Writer's Collective. Nothing from the Writer's Collective will be retained. I am also going to back up this world, in case something happens so I don't have to start from scratch. Wish me luck.
